  • How do I get Haml to work with Rails?

    - by 24hourCoder
    I am trying to get Haml to work with my Ruby on Rails project. I am new to Ruby on Rails and I really like it. However, when I attempt to add an aplication.html.haml or index.html.haml for a view, I just receive errors. I am using NetBeans as my IDE. Any help would be appreciated.

  • C# equivalent of recv?

    - by mlh
    Hello, I have a portion of C code that I am trying to port over to C#. In my C code, I create a socket and then issue a receive command. The receive command is void receive(mysocket, char * command_buffer) { recv(mysocket, command_buffer, COMMAND_BUFFER_SIZE, 0); } now, the command buffer is returned with new values including command_buffer[8] being a pointer to a string. I'm really confused as to how to do this in C# because C# Read() command specifically takes in bytes and not char. The important part is that I get the pointer to the string. Any ideas?

  • How can I determine if a composite format string is invalid?

    - by Tinister
    Per the documentation, String.Format will throw a FormatException if either (A) the format string is invalid or (B) the format string contains an index that cannot be found in the args array. I want to be able to determine which (if either) of those conditions fail on any arbitrary string and array of arguments. Is there anything that can do that for me? Thanks!

  • PHP_AUTH_USER only known in certain frames

    - by Rob
    Getting very confused by PHP_AUTH_USER. Within my web pages I have .htaccess files in every directory, controlling who can (and cant) see certain folders. In order to further customise the pages I was hoping to use PHP_AUTH_USER within the PHP code, i.e. tailor page contents based on the user. This only seems to work partially. The code snippets below hopefully demonstrate my problems. The main index.php creates a framed page with a menu structure in the top left hand corners, some irrelvant stuff in top right and then the tailor made contents in bottom frame. In top left the user is correctly shown, but in the bottom frame PHP_AUTH_USER doesnt seem to be set anymore (it returns empty and when printing all $HTTP_SERVER_VARS its not listed). Script.php is in a different path, but they all have .htaccess files in them and all other contents is displayed correctly. Why does it not know about PHP_AUTH_USER there? Running version php version 5.2.12 on chrome. index.php <FRAMESET ROWS="35%, *"> <FRAMESET COLS="25%, *"> <FRAME SRC="Menu.php"> <FRAME SRC="Something.php"> </FRAMESET> <FRAME SRC="../OtherPath/Script.php?large=1" name="outputlisting"> </FRAMESET> </FRAMESET> Menu.php <ul> <li>Reporting <ul> <li>Link1 <a href="../OtherPath/Script.php" target="outputlisting">All</a>, <a href="../OtherPath/Script.php?large=1" target="outputlisting">Big</a> </ul> <?php echo 'IP Address: ' . $_SERVER['REMOTE_ADDR'] . '<br />'; echo 'User: ' . $_SERVER['PHP_AUTH_USER']; ?> Script.php <?php echo 'User: ' . $_SERVER['PHP_AUTH_USER']; ?>

  • Redirect Using jQuery

    - by tshauck
    Hi, So I'm using jquerymobile for an app I'm creating. I have a link that if all the validation passes I'd like to go through, but if something fails I'd like to redirect. In the jquery something like this. Since it is jquerymobile the link will be a new div on the same index.html page - if that helps. $(#link).click(function(){ if(validation_fails) link_elsewhere; else return true; }

  • How to run a module

    - by Jimmy
    I have a module file containing the following functions: def replace(filename): match = re.sub(r'[^\s^\w]risk', 'risk', filename) return match def count_words(newstring): from collections import defaultdict word_dict=defaultdict(int) for line in newstring: words=line.lower().split() for word in words: word_dict[word]+=1 for word in word_dict: if'risk'==word: return word, word_dict[word] when I do this in IDLE: >>> mylist = open('C:\\Users\\ahn_133\\Desktop\\Python Project\\test10.txt').read() >>> newstrings=replace(mylist) ### This works fine. >>> newone=count_words(newstrings) ### This leads to the following error. I get the following error: Traceback (most recent call last): File "<pyshell#134>", line 1, in <module> newPH = replace(newPassage) File "C:\Users\ahn_133\Desktop\Python Project\text_modules.py", line 56, in replace match = re.sub(r'[^\s^\w]risk', 'risk', filename) File "C:\Python27\lib\re.py", line 151, in sub return _compile(pattern, flags).sub(repl, string, count) TypeError: expected string or buffer Is there anyway to run both functions without saving newstrings into a file, opening it using readlines(), and then running count_words function?

  • Vim plugin only works when file is provided as arg to launch command

    - by nsfyn55
    I am using the plugin java_getset.vim. The issue is that the plugin's commands are only available when I launch vim with the file as an argument. user@machine~: vim myfile.java If launch vim and use command-t or NerdTree to open the file in a buffer the plugin's commands are not accessible. All the filetype detection stuff is configured and working(I have syntax highlighting and indentation). The plugin source appears to be written to the letter according the the vim docs for a filetype plugin. Can anyone help me understand what changes a can make so that I can use this plugin in conjunction with Command-t?

  • mySQL: How many rows in a table before performance is affected?

    - by Industrial
    Hi everybody, Is there a "known limit" for columns & rows in a mySQL table that when passed, it can be safe to say that performance is severely affected? I've think that I had heard that there is a "golden number" that you really dont want to exceed in either columns or rows in a table. - Or is it all about the size of the index and available RAM + CPU on the server? Thanks!

  • poll(2) doesn't empty the event queue

    - by sasayins
    Hi, Im using linux as my programming platform. I am using poll(2) to know if my device is triggering an event. The first call of poll is ok, it blocks and wait for the event to happen. But in the second poll function call, it will return but it capture the event. Below are my code ret = poll( fds, 1, 2000); //2 secs timeout if( fds[0].revents & POLLIN && ret > 0) { printf("event occur\n"); } It seems the queue/buffer is not empty, im just assuming. What do you think is the problem? Thanks.
